Original commit message from CVS:
* ext/gio/gstgio.c: (gst_gio_get_supported_protocols):
Filter http and https protocols. GIO/GVfs handles them but it's
impossible to implement iradio/icecast with it. Better use
souphttpsrc or something else for this.
* ext/gio/gstgiobasesrc.c: (gst_gio_base_src_get_size):
If getting the file informations by a query fails try it with the
seek-to-end trick too.
